Readline, beginning with version 5.0, reads the stty special character
settings and binds them to their readline equivalents each time
readline() is called.  It reads ~/.inputrc once per `program'.

I made this change in response to many bug reports, over a number of
years, complaining that changes made with stty were not reflected in
the readline key bindings.

Since the traditional behavior is to read ~/.inputrc once per program
invocation, you can't have inputrc settings override stty settings
without changing readline to re-read inputrc on each call, which I
did not want to do.

Readline-5.1 makes reading the stty characters a settable option.
